19.Esther from Orphan (2009)

The Plot: Two parents become increasingly suspicious of their precocious adopted daughter when she exhibits increasingly erratic behavior.

The Kid:SPOILER ALERT She's actually not technically a kid: She's a 33-year-old woman who suffers from hypopituitarism, which gives her a childlike appearance. Oh, and she's also an escaped mental patient with a lethal record.

17.The baby from Rosemary's Baby (1968)

The Plot: After moving into a new apartment surrounded by odd and nosey neighbors, Rosemary experiences the world's strangest pregnancy and begins to suspect her child is the result of something very sinister.

The Kid: Beyond a glimpse of some glowing red eyes, Rosemary's baby itself isn't actually much of a threat... yet.

14.David Zellaby from Village of the Damned (1960)

The Plot: Nine months after a peculiar afternoon where everyone in town fell asleep at the same time, every single woman gives birth to seemingly-human blond babies. Things only get weirder as they all grow up.

The Kid: All these kids are intensely creepy, but David takes the cake when he forces one of the townspeople to set fire to himself 😱.

9.Isaac Chroner from Children of the Corn (1984)

The Plot: A young couple arrives in a seemingly deserted and decidedly creepy Nebraska town only to realize that there doesn't seem to be anyone around over the age of 18.

The Kid: Isaac is actually a young preacher who leads his adolescent cult according to the teachings of He Who Walks Behind The Rows. His demonic troop of little murderers will make you truly fear growing old.

8.Henry Evans from The Good Son (1993)

The Plot: While his father is on a business trip, Mark is sent to live with his aunt and uncle in Maine. He befriends his cousin Henry, though as the two hang out more, Henry's behavior becomes more and more violent.

The Kid: Like a modern Bad Seed, we soon learn that this isn't the first time Henry has turned on his playmates, including his own flesh and blood.

7.Gage Creed from Pet Sematary (1989)

The Plot: When his young boy is killed in a horrible accident, Louis Creed buries the body in the pet cemetery behind his house, hoping the legend of resurrection surrounding the place will bring back his son.

The Kid: In a classic case of 'careful what you wish for,' little Gage's return is far from a happy homecoming. And you thought telling your kid "no" was tough...

6.Regan MacNeil from The Exorcist (1973)

The Plot: A young girl is possessed by the devil, and it only gets worse when a couple priests are called in to exorcise her.

The Kid: Poor Regan's condition escalates pretty quickly, taking her over physically and disguising any trace of the little girl within. It's pretty scary to know your kid's still in there somewhere, buried under newfound cuss words and lots of pea soup.

4.Damien Thorn from The Omen (1976)

The Plot: When Robert Thorn's wife Katherine has a stillbirth, a priest at the hospital offers the newborn of a mother who just passed in childbirth. Without telling his wife, Robert agrees (as one does), but strange happenings and Katherine's inability to connect with the child make everyone suspicious of the kid's origins.

The Kid: Obvi Robert never received the "never accept babies from strange priests" talk, and suffers the demonic consequences. Damien's blank stares and creepy grins are enough to send chills up any parent's spine.

1.Aidan Keller from The Ring (2001)

The Kid: This fucking kid. Not only does he possess the perfect big-eyed blank stare and monotone delivery that makes a horror movie kid truly creepy, but he seems to be decidedly Team Samara from the beginning.

He's of absolutely NO help to his mom Rachel the entire movie, just glowering and staring as she frantically tries to outsmart Samara's deathly plans. And when she finally thinks she's brought an end to the curse, who's sitting there waiting to rain on her parade? SPOILER, IT'S AIDAN. Ugh, this kid.
